A Night on the Leash

The front reception of the Canterlot Spa was deserted; a small, neat room with a tall, leafy fern in one corner, and a broad reception desk facing the door. A deep blue pony sat behind it, flicking a pen back and forth between her fingers, occasionally opening and then closing the appointments book that sat in front of her. She wore a neat white spa uniform that flattered her modest breasts, a small white cap on her deep mauve mane. The clock on the wall ticked with agonising slowness as it measured the remaining minutes before six pm.

Lotus had never been quite so nervous in her entire life.

That wasn't quite true; she had been as nervous once before. That would have been the first time she and Aloe had jointly come to the conclusion that Princess Celestia, ruler of Equestria, embodiment of the sun, secretly craved to be sexually dominated, and that the only way to really get her to relax meant giving her exactly what she most desired. That had been terrifying. But, amazingly, they'd been right. The resulting sex had been all the more incredible for the risk they'd taken.

Celestia had come back to them again and again since then for her special appointments, and over time, Lotus's terror of making a misstep had faded to the point where she could almost relax as she and her twin chained the divine pony to a spanking bench and alternately flogged and fucked her. Dominating Celestia was the most powerful experience of her life. It was no doubt the same for Aloe, too.

Now it was time to push Celestia's boundaries again. All the arrangements had been made. All they had to do was go through with it.

The doorbell chimed. Lotus jerked upright in her chair, startled out of her thoughts.

Celestia stepped into the room, letting the door swing closed behind her. As always, everything else in her presence became a barely noticeable background. She was a tall mare, her skin milk white, her mane and tail flowing out behind her in an unfelt breeze. Her arms were slender, her fingers delicate. She filled an elegant grey dress to capacity, her breasts jutting out before her, her ass lightly squeezed by the small skirt into perfect shape. It ended halfway down one thigh, cut at an upwards angle. Her small feet were cradled by modest white heels, adding an inch and a half to her already impressive height. Her pink eyes sparkled as they caught the light.

She was breathtaking, every single time Lotus saw her. The sight never failed to trigger a surge of worshipful adoration in the younger mare.

She was also early. A sudden spasm of dread clutched at Lotus's chest. Was she about to cancel on them? Had her nerves gotten the better of her, driven her to decide that her fantasies should remain nothing more than fevered dreams?

Clearing her throat, Lotus asked in carefully professional tones, "Good afternoon, Princess. It's always an honour to have you here. May I ask what we can do for you today?"

Celestia stepped up to the desk, gazing down at Lotus. Her voice, as ever, was filled with gentle dignity and authority. "Hello, Lotus. I'd like you to strip me of my authority and use me like the cum-hungry bitch I am, please." She paused, then added lightly, "As long as it isn't an imposition on your time."

The rush of relief was intoxicating. Lotus leant back in her chair, savouring the echo of Celestia's words, before she spoke in a calmer, more measured voice. "You're early. We're still taking bookings for the next twelve minutes. Besides, you're asking Aloe and I to take on work outside of Spa hours. I hope a lowly cheap whore like you has the means to pay for our attention."

Celestia shivered visibly at the insult, her eyes half-closing. "I don't... actually have any coin of my own with me. I haven't whored my body to you enough," she replied softly. "Perhaps there's something else I can... give you?"

Lotus let her gaze play over the Princess with possessive familiarity. "If you expect me to enter a business arrangement with you, you'd better show me the merchandise."

Celestia nodded meekly. "Would you like to take me to a back room?"

"Weren't you listening? I have to stay at the desk. So pull down the top, lift your skirt and let me see your slutty body. Right here," Lotus commanded. It was a risk, but a small one. With Celestia's back to the door and her expansive folded wings, she could tug her dress into place if anypony happened to pick that exact moment to come in. As far as Lotus was concerned, it was more than worth the risk... and a small taste of the public humiliation that was to come.

Swallowing, Celestia glanced back at the door, and spread her wings a little to give cover to what she was doing. "As you wish," she whispered, and pulled down the bodice of her smoke-grey dress. Her heavy breasts spilled forth, contained in a delicate bra of white lace that wasn't nearly opaque enough to hide her stiffening pink nipples from the spa pony's hungry eyes. Reaching down, she pulled up the bottom of her dress, lifting it just high enough to glimpse the matching panties that hugged her broad hips. "Is this... merchandise acceptable?"

Oh, it was, it was... "No," replied Lotus firmly. "What does a cheap slut like you think she's doing wearing underwear? A whore like you is bare, ready to be fucked and used at all times. Give me your bra, right now."

There was a small tremor in Celestia's voice as she replied softly, "As you command." Reaching behind herself, she unclipped the bra, letting it fall loose, then tugged the straps down her arms and worked her way out of them without disturbing her dress. Her magnificent breasts on full display, she leant forward and laid her lacy bra in Lotus's hand, the fabric still warm from her body.

Lotus held Celestia's eyes as she lifted the bra to her face and inhaled the scent of the Princess's body, before pulling open a drawer and dropping the bra into it. "This is mine now," she said, in a matter-of-fact tone. "You won't be needing to cover those fat tits again tonight. Now give me your panties."

With a low groan, her cheeks growing pink, Celestia nodded once more. "Of... of course. I do not deserve underwear. It isn't for sluts like myself." Sliding her hands under her dress, she hooked her fingers into her panties, and tugged them smoothly down her long legs. Stepping out of them carefully, she straightened once more with the slightly damp lace crumpled in her hand.

The bell over the door chimed as it was pushed open.

Lotus's eyes met Celestia's, her heart suddenly hammering in her chest. The Princess jerked upright, yanking the bodice of her dress up and the bottom of her skirt down again, then seemed about to stuff her crumpled panties into her cleavage and out of sight. That would work. It also wasn't nearly degrading enough. "Put them in your mouth and step aside," Lotus hissed, then leaned to the right to see around Celestia.

A pink pony with a gentle blonde mane stood in the doorway, staring at Celestia's back in a kind of terrified, awe-filled stasis.

"Hello," Lotus greeted her, doing her best to keep her voice level and professional.

"I... was coming to make an appointment," the pony stammered. "I just - is that - I didn't mean to interrupt!"

Celestia had hesitated, with a briefly incredulous look on her face, but then bowed her head slightly and lowered her eyes. Her cheeks hot with shame, she lifted one hand to her mouth and parted her lips widely, pushing in the loosely folded fabric as surreptitiously as she could manage. Unfortunately for her, she simply couldn't fit all of it inside, and the end of the rolled fabric was clearly visible between her parted lips. She couldn't possibly let anypony see her like that; her depravity so exposed, her nipples jutting against the silky grey fabric of her dress.

Lotus glanced up at her, then smiled. "The Princess and I were just talking about a treatment programme for later, but she wouldn't begrudge me the time to book you in. In fact, I'm sure she'd insist you do what you came here to do."

Keeping her head turned away from the mare behind her, Celestia nodded quickly and stepped a little further to one side. "Mm-hmm," she replied, as clearly as she could through her mouthful of cotton and lace.

"O-oh! Well, if you're sure, your Majesty..." replied the pink mare timidly. "I was wondering if you had anything Wednesday afternoon?"

Lotus opened the appointments book, picking up her pen. "I do, yes", she replied with easy professionalism, relaxing from her fever-pitch of nervousness and beginning to enjoy the look of mingled excitement and terror on Celestia's face. "How does two thirty sound? It's Rosemary, isn't it?"

"Oh, um. Yes. That's right. That would be lovely, thank you. I'll just - I'll leave you to your conversation. So sorry to have intruded." Rosemary took a step backwards towards the door, then added in a rush, "It's such an honour to meet you, your Majesty!" Tugging the door open, with a second jangle of bells, she escaped into the street.

Lotus watched her go, then flicked her gaze back to Celestia. She had to act quickly, to stop the reminder of Celestia's role from bringing the Princess out of the moment. "You did very well for a silly fucktoy slut," she told her approvingly, even as a little song of terror gibbered at the back of her mind at the way she was insulting Princess Celestia. "I certainly hope you're enjoying the taste of your wet cunt. You can take your panties out of your mouth now and give them to me; you won't need them again. You're going to be bare and on display for everypony for the rest of the night."

Celestia's eyes closed, and she breathed out a soft sigh as her shoulders relaxed. Then, without further prompting, she bent forward over Lotus's desk, her breasts nearly falling out of her top, her areola showing, and dropped her panties before the dominant mare. Her pink tongue flickered over her lips, and she replied softly, huskily, "Thank you for praising your fucktoy slut, ma'am."

Picking up Celestia’s panties, Lotus fingered the damp lace, then dropped them into her drawer with the bra. Pushing back her chair, she stood up, and her gaze flicked to the elegant desk before her; the space for her legs was quite deep, and it was sealed from view from the front by the carved facade.

Could she?

"Celestia," Lotus said slowly, "You're going to be a bother standing there. Our customers will be thrown off by seeing you, and they may not even come in to make bookings at all. And it's not like a cheap whore like you can compensate us for the loss. Fortunately, I know just where you can wait." Hiking the bottom of her uniform up, gazing into the Princess's gaze the entire time, she wriggled her pink panties down her slender legs. With a short gesture, she indicated underneath the desk. "Get in your proper place and do something useful with that mouth of yours."

Swallowing, the Princess nodded meekly. "If my tongue between your legs wouldn't inconvenience you." Circling around the desk, she dropped to her knees without even stopping to check if anypony was watching, and crawled into the dark space. She had to bend herself double, her legs splayed out and her wings furled tightly, but she managed to fit herself in. Lifting her head, she closed her eyes, and added softly, "I am ready to please any cock or cunt that is presented to me, Ma'am."

"You had better be," Lotus purred, and sat back down, pulling her chair up to the desk. She shivered as she felt Celestia's gossamer mane stroking her thighs, and parted her legs, letting her outfit ride up to bare her pussy. Instantly, she felt a warm, soft tongue tracing up her thighs, seeking out the heat between her legs. Oh, fuck, she was so wet already. Biting the corner of her lip, Lotus released a breathy pant of arousal.

Ding.

A pale brown stallion pushed open the door, looking around briefly as if he expected to see something else, then approached the desk. "Uh, excuse me for asking, but... did you have, y'know, somepony special in here? Like, a special client?"

Celestia's tongue ran up and down Lotus's cunt, teasing and stroking lovingly. Lotus tried not to tense too obviously, gripping the arm of her chair hard as she replied politely, "I couldn't say anything about our clients. We protect their right to privacy. We do offer introductory packages if you'd be interested, though?"

Trying not to squirm too obviously as her slave nudged her thighs wider and lapped more urgently, holding on rigidly to her professional smile, Lotus dealt with the stallion with impeccable courtesy, though courtesy that stopped short of offering to show him inside the spa, or indeed do anything that involved standing up. Before he'd even left, another mare entered, wanting to change her appointment due in three days for one later the following week, and all Lotus could do was greet her and deal with her queries while desperately trying not to grunt or moan as Celestia's tongue was joined by her fingers.

By the time the latter mare had left with a cheery farewell, Lotus's smile was definitely a little strained. Letting herself collapse back in her chair, her head lolled back and she moaned, "Oh, oh, you slutty disgrace, you were tormenting me so nicely. No, don't stop. This is exactly where you should be. An anonymous hot mouth, ready to pleasure anypony and every pony that fills your mouth. You love the taste of my cunt, you love pleasing me..."

Through the haze of pleasure, she registered that the clock showed a minute past six, thank goodness. No more clients. Aloe would be back any moment, and then the evening could really begin. Reaching under the desk with her left hand, she seized a handful of Celestia's mane and urged her face harder against her pussy. "You're a slut, my slut, that's so good, I feel so close, I'm going to cum all over your pretty face," she groaned. The bell chimed again, and she lifted her head lazily, ready to tease Aloe for all that she'd missed.

Princess Luna stepped through the doorway, having to duck her head slightly to ensure her long horn cleared the threshold. She was a magnificent mare, deep blue, with a thrusting cleavage that filled out the star-laden gown that clung to her body, sparkling in the light. Her mane surrounded her like a nebula.

Lotus jerked upright with a gasp of surprise, her hand tightening on Celestia's mane. "P-Princess Luna!" she stammered, and felt the distinct thud as Celestia tried to lift her head suddenly and collided with the underside of the desk.

"Good afternoon," Luna said, in a polite tone that nonetheless filled the room with its resonance. "I would like to make an appointment, if that is possible."

"Yes! Definitely possible!" Lotus squeaked. Her heart hammering in her chest, for a moment she let go of Celestia's mane. This wasn't the time to take chances. But then, despite her surge of nervous terror at being caught, she rebelled against caution. When else in all the world would she have the chance to be eaten out by Princess Celestia, right in front of Princess Luna? Seizing the hidden Princess by the hair, she pulled hard, forcing her mouth back against Lotus's cunt.

A small squeak of surprised protest came from beneath the desk. Lotus's smile didn't flicker as she yanked Celestia's mane hard again, and in response, she felt the divine pony's tongue begin exploring her cunt once more. Her hips squirmed restlessly.

Luna glanced down, puzzled. "Did I hear something?"

"Just the wheels on my chair, Princess. They squeak a little," Lotus lied immediately. Flipping her dark blue appointment book open with her right hand, forcing Luna's sister against her bare cunt with the other, she added professionally, "Would you like an evening slot? We can stay a little later, and you can be assured of no other customers coming or going during your visit." Of course, that didn't mean Lotus wouldn't end up cumming during her visits. She clamped down hard on the urge to begin giggling.

"Is that the manner in which my sister visits your establishment? I have witnessed how much more relaxed she seems to be after having come here, and become impressed. I would like to try your services myself."

It took every ounce of willpower Lotus had not to moan aloud. Celestia's tongue felt so, so good, and here was Luna, innocently suggesting she should be treated the same way, strapped down, fucked, used as their personal whore... Lotus's lips parted soundlessly, and it took her a moment to find her voice again. Her cheeks burnt, and she knew she must be blushing hotly.

"Y-yes, that's right. We would be very glad to give you an appointment at your convenience, your Highness. My sister and I will do all we can to make your visit enjoyable and relaxing."

Luna nodded. "Then I shall look forward to your expert care. Would Tuesday at six suffice? I shall wake up early for it."

"That would be - wonderful, Princess! And if you find you'd like to have regular appointments, we can work out later opening hours for you." She couldn't cum, she couldn't cum, not with Luna standing right there, there was no way she could hide it! Lotus's jaw tensed as she gritted her teeth behind her pleasant smile.

"Then I shall see you Tuesday at the close of your regular hours. I look forward to it, Lotus." Luna smiled, no doubt pleased with herself for knowing Lotus's name without having to ask, and turned towards the door.

Celestia's fingers pinched Lotus's clit, sending a jolt through her that nearly pushed her over the edge. "Hng!" the blue mare gasped, maintaining her posture with terrified determination as Luna glanced back, a slightly puzzled look on her face. Lotus gripped her chair arm hard enough to make it creak in protest, holding back her orgasm with every fibre of determination in her body. Hot flushes pulsed through her, a hint of perspiration touching her forehead as she waited for Luna to ask the obvious question. It didn't come; Luna gave a slightly puzzled smile and a small wave farewell, then disappeared through the door with a soft chime of bells.

Not yet, not yet, she told herself desperately. She had to be certain Luna was gone. Count to five, and then she could give in. "O-one," she managed aloud. "Two. Thr-"

Celestia pinched her clit again.

A primal cry broke from Lotus's lips as she jerked and shuddered, holding onto her fistful of Celestia's mane like an anchor as she rode the Princess's wet-smeared face through a crashing orgasm. When the hot electricity finally died back, it left her collapsed back in her seat, mane tangled, breathing heavily. "Okay," she managed weakly, "that was good. That was very good."

Shifting forward, pushing Lotus's chair back a little, Celestia's head emerged from the shadows beneath the desk, flushed pink as she, too, panted for breath. Her lips and chin smeared with Lotus's feminine juices, she rested her head in Lotus's lap and said softly, "Thank you for using my mouth the way I deserve to be used, Ma'am."

"You stayed focused on pleasuring the cunt in front of you," replied Lotus approvingly. "Even when-" she could hardly believe it had happened! "-when Luna walked in. You kept eating me out and let me do the talking. That was perfect."

A blush coloured the royal pony's alabaster cheeks. "I may have remarked on the good care I was receiving here," she murmured, glancing to one side.

"I wonder if she might want the same kind of special treatment?" Lotus teased Celestia, and couldn't help but grin at the Princess's look of shock. "She'd look so pretty, stripped, that perfect blue body chained to a wall, clamps on her nipples, ready to get fucked senseless... we could make you watch. We could fuck both of you side by side, sisters on sisters, wouldn't that be nice?"

The bell chimed, interrupting her. Lotus pulled a face; she really had to lock the front door, if she could ever, ever persuade herself to stand up and remove the Princess's head from her lap when she deeply and truly desired nothing more than to stay like this, stroking Celestia's mane, forever. Fortunately, it was Aloe, and she flipped the sign to closed behind her, shooting the bolt across.

"I got held up!" Aloe exclaimed, lifting a little bag in mute explanation. "Do you think she's coming? ...oh." Approaching the desk as she talked, she'd obviously gotten close enough to see the multi-hued splendour of Celestia's mane spilling over Lotus's bare thighs. "Oh, I see. Hello, um, Princess."

Turning her head and pushing Lotus's chair a little further back as she crawled out from beneath the desk, Celestia looked up at Aloe and greeted her demurely, "Good evening, Ma'am. I was being used as a cheap slut to pleasure my betters." Her grey dress was mussed, her pink areola showing at the edge of her bodice.

"Well then, you could look more like a cheap slut. That makeup is far too subtle. We need to get you all painted up so the first thing a stallion thinks about when he sees your mouth is fucking it," Aloe said playfully, beckoning Celestia up.

Lotus rose from her chair and pushed it slightly towards Aloe with a grin. "She can sit here while you work on her."

"Mm, that's a good height. Now let's get you out of this dress," Aloe cooed at the Princess.

Stepping back, Lotus watched as Celestia compliantly sat down, and submitted to Aloe's array of makeup brushes and lipstick. There was a distinct nervousness about the Princess, even though she hid it well. Her bare nipples were gently taut, and she smiled as Aloe painted her lips cherry red, but Lotus could see the way Celestia's fingers toyed with each other in her lap, and there was a faint jerkiness to her breathing.

She was nervous, even frightened, of what she was about to do. So was Lotus for that matter; they were about to take an awful risk, all three of them, and if their secret got out, life would never be the same for any of them.

If it had been down to Lotus, just Lotus, then she would have wanted to keep Celestia just for herself. But this wasn't about what she wanted. This was about the fantasies that the mare in front of her had nursed for so long without ever really acknowledging, or even fully understanding, what she desired. Fulfilling those fantasies, safely, and giving her space to experience the things she'd never dared do before - that was the dominant's duty.

Stepping lightly, Lotus circled around Celestia, and rested her hands on the other mare's bare shoulders. Rubbing gently, she kneaded the tense muscles with professional care. "There, that's better. Relax, whore Princess. It's going to be a wonderful experience. You're going to please so many cocks. You're going to show off your body like the shameless slut you were always meant to be. We'll take good care of you. You can trust us."

Celestia sighed, her hands settling loosely against her thighs, and murmured a sound of wordless agreement.

Lotus hesitated. But if Celestia hadn't had sex with stallions in a long time, she had to ask... "Princess? Are you taking anything to prevent pregnancy?" She felt the answer immediately; Celestia's body stiffened under her hands with involuntary surprise.

Aloe drew back slightly, lifting her brush and giving Celestia room to reply in an undertone, "I had not... thought to. It is rare for alicorns to become pregnant, even if they were to do such things a great deal. But..."

Nodding, Lotus crossed the room and opened a small drawer. Removing a small section of root from beside several others, she turned back to lay it in Celestia's hands. "Chew this for a minute, then spit out the pulp. It should protect you from anything like that for a couple of days."

Celestia looked up at Lotus, her eyes wide. Aloe had already surrounded them with pink and blue, making them seem larger, her lashes longer, and she seemed somehow more vulnerable than ever as she said softly, "Thank you, very much. I should have thought of such precautions. Thank you for taking care of me."

Lotus couldn't help herself; her heart trembled in her chest with feelings for the beautiful, incredible mare before her, naked and exposed and offering her complete trust. "We'll take care of you. Don't worry."

Aloe picked up a small bowl and laid it in Celestia's lap while the divine pony chewed the root, ready to catch the pulp when she was done. It wasn't the first time they'd made the offer of a contraceptive to a skittish mare before an exciting evening out. "It's okay, Princess," she agreed, "We've thought a lot about how to keep you safe tonight. Otherwise, we wouldn't be getting ready to parade your bare tits and cunt around in front of a crowd of strangers!"

A subtle shiver ran through Celestia, and she nodded, bending low to spit out the remains of the root. Lifting her head, she breathed, "It's what I deserve. I want to be... humiliated and used, Ma'am. I want to be fucked."

"You will be," Lotus told her confidently. Stepping in front of Celestia as Aloe removed the bowl, she held up a broad black collar, the heavy chromed buckle and dangling D-ring gleaming in the light. A tag dangled from the front-mounted ring, the word 'Cuntslave' emblazoned on it in large, clear letters.

Celestia inhaled quickly, then nodded once more, reaching up to lift her mane away from her neck. Surrendering one end of the collar to Aloe, Lotus guided it around their slave's neck, pulling the strap through the buckle and securing it firmly. Oh, how she wanted Celestia to wear it forever! But even one night was heaven. One night was more than she could have ever imagined, not so long ago.

"You're our bitch now, cuntslave," Lotus told the Princess firmly, unable to quell the surge of nervous excitement that tingled through her body.

"Our bitch until we take the collar off again," Aloe added.

"So be good. Or else."

"Y-yes. I'll be good. I promise," Celestia replied huskily. "I promise to be your good cuntslave. Because..." she inhaled, and let it go, her eyelids fluttering, "because it makes my cunt so wet to be ordered around and used by you. I'm enslaved by my cunt."

Lotus's fingernails dug into her palm as another shudder of arousal rocked her. "Come with us. We're getting dressed, and then - then it's time to go."
